无限稀活度系数对于溶液理论工作者是一非常重要的物理量。无限稀释时,溶质一溶质间距离无限远,其相互作用可忽略不计,溶液中只存在溶质一溶剂、溶剂一溶剂相互作用力,使得理论处理简单化。而气相色谱因其测试周期短,准确度高,巳成为研究溶液的一种重要方法〔‘,一:」。本文报道了用气相色谱法测定的正庚烷、正己烷、环己烷、四氯化碳、苯、三氯甲烷、乙醚、异丙醇、正丙醇、乙醇、甲醇、乙酸甲醋、丙酮、丁酮等十四种溶质在丁二酸二正丁醋、丁二酸二异辛醋、癸二酸二正壬酗中的无限稀活度系数,并就实验结果作了讨论。
Infinite spike activity is a very important physical quantity for solution theorists. In infinite dilution, the distance between solute and solute is infinite and its interaction is negligible. There is only solute-solvent and solvent-solvent interaction in the solution, which simplifies the theoretical treatment. The gas chromatography because of its short test cycle, high accuracy, has become an important method of research solution [’, a :. This paper reports the determination of n-heptane, n-hexane, cyclohexane, carbon tetrachloride, benzene, chloroform, ether, isopropanol, n-propanol, ethanol, methanol, methyl acetate, acetone , Butanone and other fourteen kinds of solutes in di-n-butyl succinate, succinic acid two isooctyl vinegar, sebacic acid di-n-nonyl alcohol in the infinite dilute activity coefficient, and the experimental results were discussed.
